Özet

A comparison of energy, exergy rate and economic analyses for an air conditioning ON/OFF cycle and variable frequency drive (VFD) HVAC systems with heat-mass exchange calculations were performed. The study considered several key performance parameters including; energy consumption, energy saving, exergy destruction rate, exergy efficiency, CO₂ emission, the coefficient of performance (COP), and cost analysis for both HVAC systems. The total energy consumption, exergy destruction, and CO2 emission are lower when a VFD HVAC is used, as compared with an ON/OFF cycle HVAC system. The total exergy destruction decreases by more than 20%, on average, when a VFD is used when compared with the case of the ON/OFF cycle. Thus, this study reveals that, when a VFD is used, the energy efficiency and exergy efficiency increase by more than 37% and 10%, respectively.
